Our Businesses

Plastering works refer to the working with plaster. Before applying the plaster on a wall surface, our subcontractors would ensure that the wall surface is clean and free from dust and any loose part of plaster from brick laying process. Water would be sprinkled over the wall surface to ensure better adhesion of the plaster. We then mix appropriate amount and ratio of base plaster and water by drum mixers or plaster spray machines. Our subcontractors would use plaster trowel, a tool to apply, spread, shape and smooth plaster, to scoop an amount of plaster which could be held by the plaster hawk, a tool to hold and carry plaster, or directly use the plaster spray machine to spray the plaster on the wall. When the wall surface is full of plaster, our subcontractors would use nice and smooth strokes with the trowel and press onto the wall in order to spread the plaster evenly over the surface. By applying the pressure on the plaster towards different directions, the wall would be fully and equally covered with the plaster. Wall corners should be the last to be pressed.

Tile laying on internal and external walls and ﬂoors

Tile laying works refer to a series of tasks to be performed in a proper sequence in order to lay the tiles on the surface of a wall or floor. Our subcontractors would conduct checks to see whether there is any unintended colour/shade variation within the tiles. Our subcontractors would also check whether the tile adhesive to be used is compatible with the background/base of the wall/floor. Tiles would be cut neatly and accurately subject to the approval of the architect of our customers, and would be ﬁxed so that there is tile adhesion over the whole of the ﬂoor, base of the wall, and the back of the tiles. Before applying bedding material , proper adjustment may be made to give true, regular appearance to tiles and joints when viewed under ﬁnal lighting conditions. After placing the bedding material, our subcontractors would clean the surplus bedding material from joints and surface of tiles .

Brick laying works

Brick laying works refer to a series of tasks to be performed in a proper sequence in order to lay the brick blocks in position row by row to establish a proper spacing of blocks. Mortar is ﬁrst laid for full bed width and blocks are then laid one at a time by gently pressing them into the mortar bed. A line thread would be used with a line pin from one end to the other end. Checks are then conducted to ensure that all blocks are “plumb” (meaning built vertically upright) and properly bonded. Checks would also be conducted to ensure all joints are moulded and that excess mortar coming out on the edge are buttered to the cross directional joint or the head joint surface of the next block to be laid. Our subcontractors would normally close the bond, locate it near the centre of the wall and butter both edges of the closure block with mortar before laying the last closure block in the row. The above steps are repeated for each of the rows and the whole block work is to be built in uniform layers.

Marble works

Marble works refer to the laying of marble tiles to the ﬂoor. An inspection of the marble tiles would be carried out to ensure that there are no cracks or gaps in the polished surface of the tiles. Floor surface is levelled before laying the marble tiles. Our subcontractors would also mark the grid on the ﬂoor to indicate where the marble tiles would be laid. The marble tiles would then be placed according to the pattern in the grid and a layer of adhesive would be applied using a notched trowel. Our subcontractors would then lay the marble tiles ﬁrmly on top of the adhesive after the adhesive is applied. Our subcontractors would position the marble tiles in place using spacers and cut the marble tiles to fit in the edges along the walls using a wet saw in order to minimise the risk of marble tiles breaking when they are being cut. The process is repeated until all the specially sized marble tiles are cut and placed onto the adhesive. Any excess adhesive between the marble tiles is then removed and the marble tiles are left undisturbed for at least 24 hours for the adhesive to dry. Our subcontractors would then seal the marble tiles and ﬁll the spaces between the marble tiles with mortar.
